Mainstream FSes like ext3 can limit this on per-user or per-group basis,
and we had a similar thing for JFFS2, do not remember if we upstreamed
this, though. But I did send patches to the mtd ML.

FS has not idea about processes - the information about them is not
stored on the media, and it is very dynamic and unpredictable. I think
it is disaster to try to limit anything in the FS on per-process basis,
just makes little sense for me.
